In the production of hinge lid packs with rounded longi- tudinal edges, collars (10) which are present in this type of pack are preshaped in the region of longitudinal edges (13) which are also rounded. For this purpose, a scoring (embossed strip 21, 22) which extends in the longitudinal direction is applied to a web of material (14). Thereafter, the collars (10) are severed from the web of material (14) and are preshaped in the region of the longitudinal edges (13) which are to be formed. The collars (10) which have been prepared in this way can be placed on a cigarette block and be further processed in the conventional manner.
